It depends on how much you want to spend. Below is a general nib retail price range for no ban models and what I would recommend for the respect price ranges. This is only my opinion though. Good luck.
$300.00 - $350.00 ~ wasr10 (make sure you check fsb and gas block for cant, might need some dremmel time for mag fit, finish is ok, comes with 2 mags, bayo, cleaning kit, oiler)
$450.00 - $500.00 ~ Vector Classic (stamped receiver, well built, nice wood, comes with 1 mag)
$525.00 - $575.00 ~ Vector Underfolder (same as vector classic but with underfolder, comes with 1 mag)
$600.00 - $650.00 ~ Arsenal SA M7 Carbine (milled receiver, top shelf ak for the money, 90degree gas block, smooth action, synthetic furniture)
$700.00 - $800.00 ~ Arsenal SA M7 A1 (milled receiver, top shelf quality, great shooter, smooooth action, synthetic furniture)
$1000.00 + ~ Polytech Legend, Arsenal SA M7 Classic, Arsenal SA M7 underfolder.
